In 2377, Mazagalanthi, Shing-kur, Fellen and Telal were captured by the crew of the USS Defiant on Harkoum and brought to Deep Space 9 for interrogation. After Mazagalanthi learned that "Kira" was actually Iliana Ghemor, he planned to make a deal with Cenn Desca. He never got the opportunity to do so, as Shing-kur activated an implant in his brain that released a neurotoxin that killed him in seconds. (DS9novel: Fearful Symmetry)
